Will need to have a feature to block certain coupons from being scraped based on certain characters or negative keywords For example, if RTMN is in a coupon, it's an exclusive coupon and would not be used.

Will need the option to export it via CSV, XML, TAB

Will also need to be able to NOT scrape the same coupon/store/etc twice. This is going to need to crawl from one page to the next, store to store, all the way through their website/s.

Please have prior experience with data mining and scrapers and be able to show me examples of them.
